Question

Which classification describes the following system of equations?

x+y+z=6
x-y+z=8
x+y-z=0

Answer 1

Those system of equations are called the systems of linear equations with multiple variables.

Explanation:

x=5...(1)

y=6.......(2)and

- x - y + z =0.......(3)

Those systems are called systems of linear equations with multiple variables.

Those are linear equations as the maximum power of the variable is 1.

We can solve those equations with simple algebra.

Here, x = 5, y = 6 and z = x + y = 5 + 6 = 11 (Answer)
